The idea about lst is separate the branches different ways to get light the lower part of the plant.. if you just bend the main stem to one way, she will give her energy to mainstem for make it stronger to hold the rest of the plant.. If i were you, i bend the top again to opposite side before flipping to flowering.. 😉
You can lower the light a bit, I'd say on some 10-15cm from the plant, you can measure the heat or just feel it, if it's not too much on the canopy you're good ;)
